Quickstart

This guide uses the production API base URL:

https://api.eggapi.ai

1. Get an API Key

Sign in at eggapi.ai, open the dashboard, and create an API key. The public API only accepts API keys in the Authorization header:

Authorization: Bearer YOUR_API_KEY

2. Submit a Task

All currently documented public generation models are asynchronous. POST /v1/generate returns 202 Accepted and a task object.

curl -X POST https://api.eggapi.ai/v1/generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "nanobanana",
    "prompt": "A cinematic product photo of a matte green travel mug",
    "aspect_ratio": "16:9",
    "num_outputs": 1,
    "webhook_url": "https://webhook.site/your-webhook-id"
  }'

import requests

response = requests.post(
    "https://api.eggapi.ai/v1/generate",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "model": "nanobanana",
        "prompt": "A cinematic product photo of a matte green travel mug",
        "aspect_ratio": "16:9",
        "num_outputs": 1,
        "webhook_url": "https://webhook.site/your-webhook-id",
    },
)

response.raise_for_status()
task = response.json()["data"]
print(task["id"])

const response = await fetch("https://api.eggapi.ai/v1/generate", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    model: "nanobanana",
    prompt: "A cinematic product photo of a matte green travel mug",
    aspect_ratio: "16:9",
    num_outputs: 1,
    webhook_url: "https://webhook.site/your-webhook-id"
  })
});

if (!response.ok) throw new Error(await response.text());
const { data: task } = await response.json();
console.log(task.id);

Example response:

{
  "data": {
    "id": "gen_abc123def456",
    "status": "pending",
    "model": "nanobanana",
    "type": "image_generate",
    "cost": "$0.00",
    "created_at": "2026-05-08T10:30:00Z"
  },
  "error": null
}

3. Poll the Task

Use the task ID from the response:

curl https://api.eggapi.ai/v1/tasks/gen_abc123def456 \
  -H "Authorization: Bearer YOUR_API_KEY"

Completed task response:

{
  "data": {
    "id": "gen_abc123def456",
    "status": "completed",
    "model": "nanobanana",
    "type": "image_generate",
    "output": {
      "url": "https://file.eggapi.ai/images/gen_abc123def456/0.png",
      "urls": ["https://file.eggapi.ai/images/gen_abc123def456/0.png"]
    },
    "cost": "$0.0100",
    "created_at": "2026-05-08T10:30:00Z",
    "started_at": "2026-05-08T10:30:01Z",
    "completed_at": "2026-05-08T10:30:12Z"
  },
  "error": null
}

4. Check Usage

Usage endpoints require an API key:

curl https://api.eggapi.ai/v1/usage/summary \
  -H "Authorization: Bearer YOUR_API_KEY"

Example response:

{
  "data": [
    {
      "model": "nanobanana",
      "total_units": 1,
      "total_cost": "$0.0100",
      "request_count": 1
    }
  ],
  "error": null
}
